Lower electrode structure for welding



FIG. 1 is a front elevational view of the lower electrode structure,illustrating my new design;

FIG. 2 is a rear elevational view of the lower electrode structure;

FIG. 3 is a right elevational view of the lower electrode structure;

FIG. 4 is a left elevational view of the lower electrode structure;

FIG. 5 is a top plan view of the lower electrode structure;

FIG. 6 is a bottom plan view of the lower electrode structure; and,

FIG. 7 is a perspective view of the lower electrode structure.

The broken lines in the figures illustrate environmental structure thatforms no part of the claimed invention.

CLAIM The ornamental design for a lower electrode structure for welding,as shown and described.
